Hello, we found the source of this problem by analyzing the user's preferences in the Mysql table 'sogo_user_profile'.
Indeed we found the line: "SOGoSentFolderName": "INBOX \ / Drafts" who seemed suspicious. After removing it, everything returned to normal for this user. We dont know yet how this line could be generated. Best regards, Brigitte Marchiset IRIT Université Paul Sabatier Toulouse - France -- users@sogo.nu https://inverse.ca/sogo/lists
